We divide 439813 by 2
Our goal is to divide 439813 by 2.

Advancing to step 1:
2 goes into 4 2 times with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 4 from 4 and we're left with 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 2

Step 2:
3 divided by 2 is 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
If we subtract 2 from 3, we get 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 2

Let's proceed to step 3:
2 goes into 19 9 times with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 219.0
Deduct 18 from 19 and we're left with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 2

Let's proceed to step 4:
When dividing 18 by 2, we get 9 with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 2199.0
If we subtract 18 from 18, we get 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 2

Let's proceed to step 5:
2 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 21990.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 2

Advancing to step 6:
When dividing 13 by 2, we get 6 with a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 219906.0
Subtracting 12 from 13 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
2 goes into 10 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 219906.5
If we take 10 away from 10, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
The number 2 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 219906.5
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
0 divided by 2 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 219906.5
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 219906.5 with a remaining 0.0.
